Formulation, Preparation, and Storage

Carrier Free
What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: FSH alpha/beta

Follicle-Stimulating Hormone (FSH) is a 33 kDa heterodimer belonging to the glycoprotein hormone family. It is composed of noncovalently linked glycosylated alpha and beta chains. The alpha subunit is also a component of Luteinizing Hormone (LH), Thyroid-Stimulating Hormone, and Chorionic Gonadotropin. The unique beta subunit confers the protein’s specific biological action and is responsible for the interaction with the FSH Receptor (1-3). The approximately 20 kDa alpha subunit of human FSH shares 73% and 72% aa sequence identity with the mouse and rat orthologs, respectively. The approximately 21 kDa human FSH beta subunit shares 85% and 82% aa sequence identity with the mouse and rat orthologs, respectively. FSH is produced and secreted by the anterior pituitary gland. Its secretion is controlled by Gonadotropin-Releasing Hormone from the hypothalamus; however, FSH secretion can also be stimulated by activins and inhibited by inhibins (4-6). FSH works in concert with LH to regulate female reproduction; FSH stimulates follicular growth and LH induces ovulation (7). FSH can also regulate estrogen formation by inducing the aromatase enzyme that converts androgen to estradiol (7, 8). In addition, it has been suggested to have a role in postmenopausal bone loss and in the neovascularization surrounding malignant tumors (9-11). In males, FSH is critical for sperm production (12). Mutations in the human FSH and FSHR genes are associated with reduced reproductive functioning in females (2, 11). Additionally, increased production of autoantibodies directed against FSH beta has been suggested to contribute to certain types of female infertility (2). Assisted reproductive technology commonly uses recombinant FSH to induce follicle growth (7).
